These studies examine the protective effect of breastfeeding on asthma into childhood.
The association between duration of breastfeeding and childhood asthma outcomes
Longer duration of exclusive breastfeeding was found to protect against child asthma according to this study which used multivariable logistic regression to analyse breastfeeding duration and child asthma outcomes at age 4 to 6 years from women involved in the ECHO PATHWAYS consortium of prospective pregnancy cohorts. The duration of any breastfeeding had a protective linear trend with asthma, but no other outcomes. For exclusive breastfeeding, there was a duration-dependent protective association present which were stronger in dyads with children born by vaginal vs caesarean delivery, although interactions did not reach statistical significance.
